iripplication filed November 25., 1907. Serial No. 403,633.

Be it known that` I, ISAAC E.' PALMER, la'

'citizen of the United States, and resident'of' Middletown, in the county of Middlesex and State of Connecticut, have invented a new. and useful Improvement in-Hammock-Bodies, of which the following is a specification. i

"M Vinvention relates. to hammock bodies and ias for its object toi provide an arran 'ement which shall stilfenthe bed frame '0I a hammock body and prevent fit from sag-` ging or setting` and, at the same time, make it easy and comfortable forthefoccupant.

A practical embodimentV of lnyin-ventilon is represented Vin the ac'company'ing drawn s, inwhich. i

41ignre I is a perspective view of the'hfalnmock body in assembled position, Fig. 2 is a' plan rien' of the fran'na,'looki1ig at the under side showing the stiffening rods, Fig. 3 is a detail yiew of art oflt-he same, showing the arranfrements or fastening they ends ot the rods, iig. 4 is a' vertical section in the plane',

of the -line- A-A of Fig. 2%,.sliowing .the

space left at the ends ot'the rods, and Figg.

Visi, a'n'crosssection -in lthe plane 'of the lline' ,Bidi of Fig. 3'. looki ng in the direction of tlicarroivs. A

Themain body portion is denotedjby l and 1t ,has endportions 2 which are eon' nected by cords 3 to rings or eyes 4 for suspending the hammock body.l The said main body portion and itsfends may be of any convenient sha pe and made of any suitable inaterial, such, for instance, as canvas, woven fabrics, etc. A

The bottom frame is denoted by' 5 and it is formed to Iit in the main body portion, as shown in Fig. l, and rest on the bottom of 40 saidbodyiportion. The frame 5' is beveled on its upper side, its outer' edgebeing thicker than its vinner edge, making the frame stiff and at the same time light and also forming 'a natural seat for the mattress. This frame portion preferably make of wood alt-houfrh metal or other stifl:l -materia-l 'may readily e used and4 theusual'laeing cord .6 is strung from one side to the other of the .frame 5 in order that the mattress or Vother support of any well known or approved construction,

not .shown herein, may rest yieldinfrly on this bottom frame. In hammock bo ies ofv this class heretofore made the -frames have had a-constan't tendency to sag: o1" set and this has been a great and very objectionableof the sides ofthe said frame.

fault because it has caused apermanentdi.=- tortion of a hammock body, increased the Wear of Acertain parts and made the hammock body uncomfortable tothe user. To .obviate Vthis defect, I provide the frame of the hammock body with stiilening barsor rods 7, which, in the present case, are arranged longitudinally along the under sidel These rods 'T are set in grooves Sin the side portions 9 of :the frame, in the pri-sent instance, so as to be Hush with the faces of said side portions, and

are ,slidably held in position by the headplates 10 which are fastened to theside portions 9 of the frame 5 over the extremities of said rods 7, These head plates l0, I pret'l erably make substantially flat and secure them to the `frame in the saine plane therewith; but I prov-ide said-plateswith a tooth orprojection 1.1 which enters the groove 8 and rests against the en'd thereof and serves asa protecting plate for the end'wall of said groove.

In the form shown, the rods 7 are made a little shorter than y t-lxencorresponding grooves so that each rod may he allowed :i

Aslight longitudinal sliding movement in its groove, shown in Fig. 1, andthe rods are preferably arranged two on each-side piece t) and overlappingeacli other along the cen? tral portion of said side pieces 9 but extend-` -ingl singly for `a distance towardtlie oppo- Asite ends of each'side piece, thereby predileing a greater stitfeningefect along` the central portion 'of the side pieces than at the endsv thereof. y

It will he plainly `seenl that when the .frame 5 is placed inthe iria-in body portion 1 and -a weight is caused to rest upon said frame, the tendency of the frame to sag will be resisted. by the rodA 7; -These rods, however, will allow .the VframeA to sag or give .slightly and 1n. so doing the rods will slide aloi'ig o n the 4head plates 10but4 all undue 'distortion of the frame. will.4 be absolutely prevented.

By giving the rods a slight longitudinaL play in their grooves, I obviate any loosening or tearing away {of the head plates 10,

Vwhich 4would tend to'occur .if the rods were held immovably in place; because a small bending4 on the )art of the frame" would cause a 'considerano longitudinal strain on the rods..

Bymyxstrncture I eliminate allthe objectionable defects of such aA strain and at the lsame time impart aslight yielding propert' to the framefwhich is desirable.

hen the weight is removed from the 51tr-aine, the head plates will allow 'the rods to -re'tiil'n to their normalvposition and so keep the frame from becoming permanently distorted. A

The rods' 7 may be of any suitable mate.-

' and they may be plaoed'on the frame in feasible manner but I preferably make then) of'steel and place two of them on each` side' portion-of the frame 5, each two being substantially'parallel to each other.

- 'It is to be understood that I do not conline inyselfto'the struct-nre -herein shown and .-described,-as it: i's only Oneway of carrying ont my invention;

What I claim' is:-

1. Iii combination, a hammock body,4 a

frame .fitted to the body and comprising sides.-

and ends Secured together at the' corners and stitfening rods y extending longitudinally falong the under faces'of thefsides of the frame inl grooves formed therein, thesaid rods having 'a limited free longitudinal sliding. movement in 'the grooves.

.2. `In lcombination, a hammock body, a.

frame fitted to the body and comprising sides and ends l secured together at the corners 30 with their ed es directed inwardly vand outwardly in a orizont-al planeand overlap-v ping stitfening rods secured to the under sides of the frame in grooves formed in the said sides, the' said rods 4I iaving a limited 35 free longitudinal movement in thel grooves..

-3. In combination, a hammock body, a

`frame-f itt ed tothe body and comprising sides"l and ends'secured together at the corners, the said sides and ends having their upper faces 40 beveled and arranged with their thinner 'edges directed inwardly and their thicker edges directed outwardly and stii'ei'iingl rods secured in grooves formed inthe under sides ofi-the vsides of the 4frame and" having a limr ited lfree longitudinal, 4movement 1n said grooves.

"In testimony,l that I claim the f foregoing 'as my invention, I have signed my naine in presence of two witnesses, this .21st day-0f v50 November 1907.
